Abstract
The utility model relates to a high temperature insulating electric wire for 500 DEG C, which comprises a conductor core in the center of the wire. The high temperature insulating electric wire for 500 DEG C is characterized in that the external layer of the conductor core is asbestos; alkali-free glass fibers wind a cladding; the external layer of the cladding is a mica tape layer; the external layer of the mica tape layer is the cladding of the weaving alkali-free glass fibers; the external layer of the cladding of the weaving alkali-free glass fibers is the coating layer of the high temperature resistant synthetic paint, and each cladding on the external side of the conductor core is appressed and is not provided with the gap shape. The utility model has the advantages that 1. the high temperature resistant performance can reach to 500DEG. C 2. the service life is long 3, 4. the price is lower than the similar foreign products.
Description
The utility model belongs to a kind of high-temperature insulation electric wire, particularly 500 ℃ of high-temperature insulation electric wires of ability.
At present the soft type high temperature electric wire in international market upgrade day by day, replaces gradually " armoury wire ", owing to uses the nonmetal covering that is, vibration is defied in bending winding arbitrarily, installs and change very convenient, receive praises from customers, and performance reaches the armouring index.The U.S.'s this aspect work exploitation early and kind maximum, temperature resistant range is also wide, therefore the Aero-Space career development is fast, the chemical industry prosperity is various organic and inorganic material is more complete, promoted the development of aspects such as high temperature electric wire cable, but its cost is higher.It is below 250 ℃ at application of temperature that China powers with the high-temperature insulation electric wire at present, adopts the organic material covering, and application of temperature is in the employing inorganic material structure below 450 ℃, has that quality is hard, an out of use shortcoming under the dynamic condition.
The purpose of this utility model is to provide a kind of 500 ℃ of high-temperature insulation electric wires, it adopts advanced usefulness coating organic and that inorganic material is synthetic to make insulated cladding, make heat resistance bring up to 500 ℃, and can guarantee quiet, the dynamically normal use of electric wire, a kind of every technical indicator reaches international standards, and fills up the high-tech achievement of China's high temperature electric wire blank.
The technical solution of the utility model: a kind of 500 ℃ of high-temperature insulation electric wires, the conductor cores that comprises the line center, it is characterized in that outer in conductor cores is asbestos, alkali-free glass fibre lapping layer, this lapping layer skin is the mica belt, the mica belt is outer for weaving the alkali-free glass fibre covering, and braiding alkali-free glass fibre covering skin is high temperature resistant synthetic paint coating; Between outer each covering of above-mentioned conductor cores for being adjacent to no gap-like.
Superiority of the present utility model is: 1, resistance to low temperature, water resistance, oil resistance, withstand voltage properties are well, and resistance to elevated temperatures is under 500 ℃ of operational environments, and insulation resistance is greater than 400M Ω m; 2, long service life, the use of 500 ℃ of environment static state can be continuous more than 2 years, and 400 ℃ can be used for a long time, and adding the nickel wire braid can dynamically use; 3, make and close in extensive rangely, can be used for modernization such as electric power system, metallurgy, chemical industry, electronics, automobile, power plant equipment; 4, price is lower than external like product.
Further specify present technique below in conjunction with drawings and Examples.
Accompanying drawing is the transversal profile structural representation of the related 500 ℃ of high-temperature insulation electric wires of the utility model.
Wherein 1 is conductor cores, and 2 is lapping layer, and 3 is the mica belt, and 4 are braiding alkali-free glass fibre covering, and 5 is high temperature resistant synthetic paint coating.
Embodiment:
A kind of 500 ℃ of high-temperature insulation electric wires (seeing accompanying drawing), the conductor cores 1 that comprises the line center, it is characterized in that outer in conductor cores is asbestos, alkali-free glass fibre lapping layer 2, this lapping layer skin is a mica belt 3, the mica belt is outer for weaving alkali-free glass fibre covering 4, and braiding alkali-free glass fibre covering skin is high temperature resistant synthetic paint coating 5; Between outer each covering of above-mentioned conductor cores for being adjacent to no gap-like.
Claims (2)
1, a kind of 500 ℃ of high-temperature insulation electric wires, the conductor cores that comprises the line center, it is characterized in that outer in conductor cores is asbestos, alkali-free glass fibre lapping layer, this lapping layer skin is the mica belt, the mica belt is outer for weaving the alkali-free glass fibre covering, and braiding alkali-free glass fibre covering skin is high temperature resistant synthetic paint coating; Between outer each covering of above-mentioned conductor cores for being adjacent to no gap-like.
2,, can install the nickel wire braid additional when it is characterized in that the dynamic use of said electric wire by the described 500 ℃ of high-temperature insulation electric wires of claim 1.
